Cambridge startup AlertMe's motto is "Creating Smart Homes". It specialises in offering sensors to control objects and services in the home. This includes: an energy-monitoring system that allows you to look at power consumption, cost and your carbon footprint; a smart heating-system that lets you control heating remotely through your phone; and a "super app" for your home that uses motion detectors, door and window sensors, smoke and gas alarms, and cameras to remotely monitor your home security.
